no doctors(family or primary), visited local health care center 2 times for flu fever treatments. I don t have medicines in my house, not even a pain killer. Dear Dr. I got the similar question about left hand knuckles turned darker looking like the 4 have been burnt, grilled or smoked. How I found it-one night when showering, they just shocked me and looked so weird! It has been 2 weeks now, and I do not feel any thing except they look ugly, funny and the skin is rough. I don t have insurance so would you please help me with this strange thing? I am a vegetarian(90% of my food is USDA certified organic products), never smoked, size 10, 5 5 H, walk at least 4 hours a week and healthy. Have not needed to see a dentist for 15 years, and only needed to get treatment for flu twice in the past 15 years. Your help and kindness heart are gratefully appreciated.
